WALL-SOCKET.

Specification of Letters Patent. Application filed August 14,1913. Serial no. 784,668.

To all whom it may concern:

Be it known that 1, JOHN EDWARD Osman, a citizen of the United States of America,

and a resident of Brooklyn, county of Kings,

and State of New York, have invented certain new and useful Improvements in Wall- Sockets,of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to wall plugs or sockets such as are driven into holes in walls, floors or-other structures to provide anchorages for threaded bolts. a

The object of this invention is to provide a simple and inexpensive device which has advantages over those which hitherto have been known. A

Referrin to the drawings, Figure 1 is a sectional e evation of a wall with a wall socket which embodies my invention embedded in a hole therein and this figure also shows an object secured to the wall by. means of a bolt screwed into the socket. Fig. 2 is a sectional longitudinal elevation, and'Fig. 3

I spectively,

an end view of a wall socket made according to my invention but of slightly difierent form from that shown in Fig. 1. Fig. 4. is

an end elevation of a socket-which is elliptical in cross section. Another form of my 1nventlon is shown in sectlonal long tu mal elevation and end v1ew respect vely in Figs.

5 and 6. In Figs. 7 and 8 another modification,

with the outer fins or ribs placed onl at the ends of the device, is shown in longitudinal section and in transverse section rethe section in Fig. 8 being taken on the line 88' of Fig. 7t Another modified construction is shown in longitudinal elevaa tion partly in section in Fig. 9, and in end view in Fig. 10. These two figures show the fins or holdin ribs normal to the axis of the device. T ese ribs are shown in helices in Figs. 11 and 12 of which Fig. 11 is a longitudinal elevation partly in section and Fig. 12 is an end elevation. V Like characters of reference designate corresponding parts in all the'figures.

In all of t e modifications shown, the plug or socket comprises a circumferentially continuous hollow shell 10, the inside of which is provided with means for receiving the threads of a bolt/and from the outside of which project a plurality of parallel over lapping holding fins or ribs which are more or less flexible. These fins are designated by the reference numeral 11.

In Fig. 2 the fins are tapered so that the portions of them at the outer end of the shell stand out from the shell a greater dis- 'tance than do those. portions which are at the inner end of the shell. In this and some of the other figures of the drawings the shell is internally threaded as at 12- to receive the threaded shank of abolt 13, or other desired device. It is sometimes desirable to countersink the outer end of the shell as at 14: so that if the plug or socket is driven into a hole with a hammer, the threads 12 will not be injured thereby. I Before describing'the modifications illustrated in the other figures of the-drawings, T will describe the manner in which this de vice is used, referring particularly to Figs.

1, 2 and 3. In Fig. 1, 20 designates a wall of concrete or other, material into which a bolt cannot be conveniently screwed, and-21 is a hole drilled therein to a depth somewhat in excess of the length of the socket. The diameter of thishole is slightly less than the external diameter of the socket. The socket is then driven into the hole which causes the fins to be pressed inward a suificient amount to allow the socket to enter. If the fins are tapered longitudinally as they are shown in Fig. 2, the plug will enter the hole with but little resistance, which resistance will in-v crease as the plug goes farther into the hole. The compressed overlapping-fins form an I ratenteaaa naaeia. I

efi'ective means for holding the device in the wall or other structure so that it will remain in the wall. It isto be noted that the fins are inclined from the periphery of the shell in a common direction corresponding'with the direction given a right-handed screw when turned into place. edges of the fins to oppose any tendency of the shell to turn with'the bolt.

The device may be made of either hard or soft metal. If of soft metal it may be either internally threaded as shown at 12 in some of the figures, or it may be so arranged that the threads when it is in-:

the bolt will cut serted. For example, the bore of the shell may be elliptical or of a form the crosssection of which is a curved plane of nonuniform diameter, as is shown at 15 in Fig. 1. ,The external cross-section of the shell shown in Fig. 4. and designated by 10*, is also a curved plane of non-uniform diameter. It is obvious also that the shell itself may be cylindrical with the line drawn through the outer edges of the fins of the This causes the form shown in this figure. Another convenient construction in which the bolt may cut threads is illustrated in Figs. 5 and 6, in which are internal longitudinally disposed projections or ribs 16. In Fig. 5 the shell 10 is externally tapered and the parts 11 of the fins parallel with the outer surface thereof. The parts 11 of the fins flare outwardly as shown. This is a distinct advantage, for in drilling holes such as that shown at 21 in Fig. 1 by hand, the outer part thereof is apt to be of larger diameter than the rest of the hole and the flare on the ribs not only centers the socket but more closely fills up the outer end of the hole. Similarly flared fins are shown at 11 near the outer end of the shell in Fig. 7 but these are not continuous. Near the inner end of the shell are other fins 11 while the intermediate part of the shell is in this case without fins.

This invention is not limited to longitudinally disposed holding fins. In Figs. 9 and 10 for exam le, I have shown similar overlapping hol ing fins or ribs 17 which are at right angles to the axis of the shell. And in Figs. 11 and 12 the fins, designated by 18 .are helically disposed.

I have illustrated several modifications of the invention to show that it is not limited to any specific form or construction, but

that many designs and devices may be made within the scope of the claims.

What I claim is 1. A wall socket comprising a hollow shell having overlapping compressible holding'fins projecting from itsouter surface whereby when the socket is introduced into a recess having hard walls compression of i the fins serves to anchor the socket.

' said shell for receiving the threads of a bolt whereby when the socket is introduced into i a recess having hard walls compression of .the fins servesto anchor the socket.

ternally threaded shell having longitudi- .nally extending overlapping compressible holding fins projecting from its outer surface whereby when the socket is introduced into a recess having hard walls compression of the fins serves to anchor the socket.

ternally threaded cylindrical shell having longitudinally extending overlapping tapered compressible holding fins projecting from its outer surface whereby when the socket is introduced into a recess having hard walls compression of the fins serves to anchor the socket.

7. A wall socket comprising a circumferentially continuous hollow cylindrical shell having longitudinally extending overlapping compressible holding fins projecting from itsouter surface and extending over the length of the shell, said fins being tapered longitudinally and transversely, and means within aid shell for receiving the threads of a belt whereby when the socket is introduced into a recess having hard walls compression of the fins serves to anchor the socket.

8. A wall socket comprising a circumferentially continuous hollow internally threaded cylindrical shell having longitudinally extending overlapping compressible holding fins projecting from its outer surface and extending over the length of the shell, said fins being tapered longitudinally and transversely, the outer end .of said shell being provided with an internal recess whereby .when .the socket is introduced into a recess having hard walls compression of the fins serves to anchor the socket.

In testimony whereof, I have hereunto set my hand in the presence of two subscribing witnesses, this 29th day of July, 1913.
